Anti-gay activist Peter LaBarbera, president of Americans For Truth About Homosexuality, argues against gay marriage because gay sex is “dangerous and unnatural.”

Appearing on Liberty Counsel's Faith and Freedom radio program, LaBarbera railed against allowing gay and lesbian couples to marry, saying such unions soil the institution of marriage.

“This was the sin that dare not speak its name several decades ago – that's what it was,” LaBarbera said. “Think about where we've come. Now they want to attach the sin of Sodom to marriage. A behavior which Dr. John Diggs … Diggs said that sodomy, it's almost as if homosexual sodomy was created to spread disease. That's how dangerous and unnatural this lifestyle is. And yet we're being told that it can now be attached to the noble institution of marriage. When a nation does that, when a nation embraces such confusion and such evil it is on a moral decline.” (The video is embedded on this page. Visit our video library for more videos.)

LaBarbera endorsed a Christian revival to counter “the sin movement.”
